Diaphragm expansion vessel REFLEX N-600, 600L, 6 bar / 70°C, threaded connection male R1", dark grey, for heating and cooling systems, standing, with non-replaceable semi-membrane 8218400

Diaphragm expansion vessels – stability and safety of the installation

REFLEX N-type expansion vessels, with a non-replaceable diaphragm, are a key element of closed heating and cooling systems. Their task is to compensate for changes in liquid volume resulting from temperature fluctuations, maintaining constant pressure in the system. This ensures the correct and safe operation of the entire heating or cooling system. The construction based on a diaphragm separating the water part from the gaseous part prevents gas from penetrating the water, which affects its quality and efficiency.

This model, REFLEX N-600 with a capacity of 600 liters, is designed to operate at a maximum pressure of 6 bar and a temperature of 70°C. Made of high-quality materials, it guarantees durability and reliability even in demanding operating conditions. The standing construction with welded legs provides stability and facilitates installation.

Characteristics and application

The REFLEX N-600 expansion vessel finds application in:

• Heating installations: single-family homes, multi-family buildings, commercial facilities.
• Cooling systems: providing stable operating conditions for cooling devices.
• Solar systems: compensating for changes in liquid volume in solar installations.
• Underfloor heating: maintaining optimal pressure in the underfloor heating system.

The GZ R1" threaded connection facilitates integration with the existing installation. It is extremely important to comply with the PN-EN 13831 standard and the pressure equipment directive 2014/68/EU, which confirms the high level of safety and reliability of the device.

Key features and benefits

• High capacity (600 l): ideal solution for larger heating and cooling installations where a large volume reserve is required.
• Durable construction: made of high-quality materials ensures long-term operation without the need for frequent replacement.
• Non-replaceable diaphragm: eliminates the need for servicing and replacing the diaphragm, reducing operating costs.
• Compliance with standards: meeting the requirements of the PN-EN 13831 standard and the 2014/68/EU directive guarantees safety of use.
• Stable pressure: maintains constant pressure in the installation, protecting devices from damage caused by pressure fluctuations.
• Easy installation: the standing construction and GZ R1" threaded connection facilitate integration with the existing installation.
• Operating parameters: Initial pressure of 1.5 bar ensures optimal system operating conditions from the start. The height of the vessel is 1531 mm and the diameter is 740 mm - these dimensions should be taken into account when planning the installation.

Remember to select the expansion vessel correctly to the parameters of the installation – too small a capacity can lead to pressure problems, and too large – to unnecessary investment costs. Choosing REFLEX N-600 is an investment in a stable and safe operation of the heating or cooling system for years to come!
